RAILWAY-RAlL-JOINT CHAIR.

SPECIFICATION forming part of Letters Patent No. 763,075 dated June 21, 1904.

Application filed March 10, 1904.

To all whrmt it may concern.-

Be it known that we, AMos SAU nERs'and ARTHUR W. IVILMOTH, citizens of the United States, residing atRiChardSon, in the county of Dallas and State of Texas, have invented a new and useful Railway-Rail-Joint Chair, of which the following is a specification.

This invention relates to the railway-chairs connecting the adjacent ends of railway-rails, and has for its object to improvethe construction and produce a device of this character of increased strength and durability and which will effectually prevent deflection of the rails at the joints, and thereby preserve the uniformity of the line of the rails.

With these and other objects in view, which will appear as the nature of the invention is better understood, the same consists in certain novel features of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which corresponding parts are denoted by like designating characters, is illustrated the preferred form of the embodiment of the invention ca: pable of carrying the same into practical op eration, it being understood that the invention is not necessarily limited thereto, as,va-. rious changes in the shape, proportions, and general assemblage of the parts may be resorted to without departing from the principle of the invention or sacrificing any of its ad vantages, and the right is therefore reserved of making all the changes and modifications which fairly fall within the scope of the in-,-.

vention and the claims made therefor.

In the drawings thus employed, Figure 1 1s a side elevation, Fig. 2 is a plan View, and

Fig. 3 is a transverse section, of the improved joint applied. Fig. 4 is a perspective view of the base-plate detached."

The rails 10 11 and ties 12 are of the usual form.

The improved device consists of a base-plate 13, extending beneath the rail ends and over two or more of the ties adjacent to the rail ends and with lateral extensions 14 at the ends projecting over the ties, the plate being secured to the ties by the usual spikes 15.

Serial No. 197,438. (No model.)

Between the lateral extensions the edges of the plate 13 are bent outwardly and upwardly and thence inwardly and downwardly, as at 16 17, and the plate is also provided with a depending fin 18, bearing by its ends against the adjacent ties 12. Disposed upon opposite sides of the rail ends are clamp-plates 19 20, secured in position by the usual transverse clamp-bolts 22 and extending over the tieflanges of the rails .and with their outer edges 23 24 bent upwardly and outwardly for engagement with the turned-over edges 1617 of the plate 13, as clearly shown in Fig. 3. The clamp-plates 19 20 will preferably extend the full length of the plate 13 and with spikerecesses of the usual form to receive the shanks of the spikes 15,:and thus assist in supporting the. clamp-plates By this simple means it will be obviousthat a very compact, strong, and durable joint is produced which not only firmly connects the rail ends and prevents all longitudinal movement, but also serves as a chair to prevent deflection or sagging at the joints, thus efliectually supporting the rails and maintaining a uniformity in the line of the rails.

By distributing the strains over two or more ated andthe stifiness or rigidity of the joint materially increased.

The lateral extensions 14: at the ends of' the plate 13 also materially increase the bearingsurface of the plate and correspondingly decrease the tendency to deflection. r

The plate 13, together with the lateral extensions 14' and bent-over edges 16 17,will preferably be in one piece pressed into required shape.

edges slitted so that-the central portions may be curled upward, inward, and downward to engage the clamp-plates of the rail and the end portions flattened down to rest upon the ties and form attaching members, the expense of manufacturing the device is greatly reduced without sacrificing its strength. This is a consideration of vital importance in such a thing as a railroad-chair, where cheapness must be combined with strength.

of the ties the tendency to deflection is obvi- By making the plate inone piece, with the Having thus described the invention, what portion to engage rail-clamp members, and
